I have exported a pair of cookies from Firefox that are valid for the URL in question and tried accessing/downloading the protected content off that address, but the end result is a return to the login page. I have tried doing the same thing for 3 other websites with similar outcome. Any clues as to what I might be doing wrong?

The syntax I'm using: wget --load--cookies=FILE URL
